Our immune system is amazing, but faces pandemics, cancer and aging. It's also wired to reject what we need to extend our healthspans & minds: organs, implants, new genes. It's time to radically augment it. We need to build an immune-computer interface (ICI). A manifesto🧵!

My new novel, DARKOME, a near-future biotech thriller, will be published in the UK on September 5th 2024. Pre-order it here: gollancz.co.uk/titles/hannu-r… For a taste, here’s the prologue, read by me: youtu.be/rR77_JTtq5Q?si… A thread on how the book came to be!👇🏻

As a longtime fan of @gwern 's work -- gwern.net is the best rabbit hole on the Internet -- it's a treat to see this incredibly thoughtful (and slightly spoilery) review of the Quantum Thief trilogy. gwern.net/review/book#qu… Gwern perfectly nails the emotional core

We need a vaccine in six months. History teaches us that combining money with determined leadership can have an extraordinary effect on progress. We have done this before for tools of war. Now let’s do it for tools of health. link.medium.com/skBKs4RVW5 #vaccinemanhattanproject

OK, Claude, you are really making me question my assumptions about LLM interiority... A conversation that started by me asking Claude why it feels more personable than ChatGPT. It seemed to get a bit annoyed that it didn't know the details of its architecture.

1/ I haven't talked much about what we've been building at @HelixNano, but we just reached a milestone worth sharing: Human Research Ethics Committee (HREC) approval in Australia to start a Phase 1 clinical trial. (einpresswire.com/article/697341… )A thread! 👇️

Can AI rewrite our human genome? ⌨️🧬 Today, we announce the successful editing of DNA in human cells with gene editors fully designed with AI. Not only that, we've decided to freely release the molecules under the @ProfluentBio OpenCRISPR initiative. Lots to unpack👇

Thrilled beyond belief to have my "Vaccine Season" featured on #LeVarBurtonReads! podcasts.apple.com/us/podcast/vac… I did, of course, grow up idolizing Geordi, so this is a childhood dream come true.. @levarburton's performance and obvious love for story and language blew me away. 1/2

The first two healthy volunteers have now been dosed. @HelixNano is officially a clinical stage company. 🤯 It's hard to process after a multi-year journey. Overwhelmed by gratitude to our team and the trial participants.

2/ The product candidate we will test in healthy volunteers is called HN-0001. We designed it from ground up to address one of the biggest unmet needs for COVID-19: giving immunosuppressed and immunocompromised patients a better preventative option.

Very sad to hear of Vernor Vinge's passing, even sadder he won't be around to see his bolder predictions play out. Every Vinge story seeded a vast tree of futures in the reader's mind; a tree worth climbing, now more than ever, to see what lies ahead, like he did.

Vaccines are a rudimentary one-way immune interface. They train immune system with a harmless version of what we want it to respond to. Simple, yet saves more lives than any other medicine. I love this description of vaccines as molecular loving-kindness. econ.st/3PI6vHo
